Clearly, removal of hardware support needs to be carefully researched to ensure that we are not crippling any supported platforms. Kevin, can you clue us in on what serial chipsets need to be supported in Nevada? -- meem _______________________________________________ opensolaris-code mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/opensolaris-code
